Regarding the "Return" key question. Everything is working fine for me. Each tap of the Return key sends me to a new line like it always has & should.
Thank you for your patience, Nick.
1. I think we can discard the autocapitalise issue. I think it is an iPad issue. Anyway, it's variable and not a big deal
2. The hit-return-three times issue to get a double space/paragraph has "solved itself", just today. But only on the iMacs. Why? How/ Don't know. It was certainly annoying me.
3. The issue of inserting a cursor to correct spelling errors where it Autocapitalises is confined to my iPad Pro. It persists on the iPad but not now on my iMacs.
So, either you "had a cunning plan" and corrected something (I always give you credit, Nick) for issues 1 and 2 above; or, sadly, I have been wasting your time.
.
I certainly didn't mean to, as these "difficulties" were there on all devices but have resolved somehow. Only the iPad Pro things are still there and that could be in settings.
Anyhow, thank you for your kindness & attention. Sorry to have bothered you.
